A 30kg mass is tied to a uniform rod whose mass and length are 80-kg and 8-m, as shown below. The rod is attached to the floor via a hinge and makes an angle of 70° relative to the ground; a massless string is also attached to the rod at the ¼ point of the rod and makes an angle of 20° relative to the horizontal. What tension must be provided by the rope so that the system remains in stationary? If at some point the string breaks, what will be the angular acceleration of the system the instant that the string breaks?

Need help in 15 minutes. ASAP. A 75-kg block is attached to a cable. The cable is then attached to a rotating assembly with a mass moment of inertia of 18 kg-m^2. The bearing friction applied at the rotating assembly equivalent to a couple of 45 N-m CCW. The block's downward speed is initially at 2 m/s. What is the total work done by the system after the rotating assembly has rotated 1.5 radians CW? What is the speed of the 75-kg block after the rotating assembly rotated 1.5 rad CW?
A mass m₁ = 2.0 kg is suspended over a pulley of moment of inertia, I₁ = 0.010 kg-m², and a radius, R₁ = 0.10 m, and is attached with a massless rope to a mass on a horizontal table, m₁ = 2.0 kg. This mass is itself attached to another suspended mass m₂ = 4.0 kg again with a massless rope over a pulley of moment of inertia, I₂ = 0.040 kg-m², and a radius, R₂ = 0.20 m. (a) Find the velocity of each mass when my falls a distance of 1.00 m (the masses start at rest). (b) There is now friction on the horizontal table, µ = 0.74. Again find the velocity of each mass when my falls a distance of 1.00 m (the masses still start at rest).
